To all whom it may concern:

Be it known that 1, Louis J. DEASY, a citizen of the United States,residing at Cincinnati, in the county ofHamilton and State of Ohio, haveinvented. certain new and useful Improvements in Trolley-Poles,- ofwhich the following is a specification, ref-' erence being had to theaccompanying drawmgs.

This invention relates to new and useful improvements in trolley polesand more particularly to a spring actuated trolley pole, the main objectof the present invention being the provision of a trolley pole which isnormally retained in an upright position for engagement with the trolleywire andis provided with means whereby should the pole become disengagedfromthe trolley wire, it will be forced downwardly toward the top of theguard and will thus be entirely out of j the way from cross-line wires,over head bridges or. the like and is provided with means adapted to bemanually operated to return the pole to its normal operative position.

Another object of the present invention is the provision ofa device ofthe above character which will possess advantages in points ofefficiency and durability, is inexpensive to manufacture and, at thesame time, is

simple in construction and operation.

WVith the above and other objectsin view, the invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification and claims.

1n the accompanying drawings forming a part of this application, Figure1 is a side elevation of a trolleypole constructed in ac-' .cordancewith my invention, parts thereof being broken away and illustrated incross section. Fig. 2 is a top plan view. Fig.3

is a rear end elevation. Fig. 4 isa detail side elevation, illustratingthe device in 'an inoperative position. Fig. 5 is a detail end viewillustrating the device in an operative position and Fig. 6 is a detaillongitudinal sectional view of the movable cylinder. 7

Referring more particularly to the drawings, 1 indicates a trolley guardwhich may be of any general-construction and mounted upon the topthereof, is a plate 2 which is provided with an upwardly projectingannular flange 3 forming acir cular bearing socket in which arearrangedt-he ball bear- Specification of Letters Patent.

j ingsd. Extending -centrally down through this bearing socket, 1s apivot pin 5 which is carried-by a movable basemember 6. Secured to thelower face of the base member 6, is a bearing plate 7. which is adaptedto rest upon the ball bearings 4, whereby to of the plate 6, is anupright stop member 8 andformed integral with the plate and the member8, is a cylinder 9. of the memberS is bifurcated to form two spaced arms10, between which is pivotally the main body portion of the trolley poleand. projecting outwardly from one end thereof, are the spaced arms 12,between which the pulley 13 is mounted.

of said coil spring bearing against the end of the movable cylinder Handthe other end ment of the cylinder 14, the spring 15 will be placedunder tension toforce the cylinder 14 outwardly, when released. Itwillbenoted that the screw member 16 #may be readily adjusted within thecylinder 9 to within the cylinder 9 is a piston rod 17, the innerend ofwhich is connected'to the outer end of the movable cylinder 1d.Theotherend of the piston rod is adapted to work within a suitableopening formed in the central portion ofthe screw member 16 and securedto the outer end of the piston rod by means within the cylinder 9.Formed upon the end of the body plate 6, opposite the member. 8, is anupwardly projecting post 20, the upper spaced arms 21 and mountedforrotary before passing over the pulley 1.3.

mounted the body 11. The member 11 forms Mounted for reciprocationwithin the thereof bears against the movable screw member 16. Thus upon{the IDWEllClIllOVQ- of the link 18, is a cord 19, whichis adaptedv tobe used to reciprocate the cylinder 14-.

end of which is bifurcated to formtwo Supported by the body 'member ll,is a trolley pole 23, on the outer end of which permit of a free rotarymovement of the 7 base member 6. Formed upon the one end p The upper endi movement between said arms,.is' a pulley 22 around which the cord19 isadapted to pass,

11c before being passed downwardly towardthe guard. From this it "willbe apparent that F upon downward pulling movement of the cord 19, thecylinder 14 will be reciprocated within the cylinder 9. Formed integralwith the body member 11 and projecting rearwardly therefrom, is asubstantially hookshaped member 27, the inner end of which is providedwith a recess 28 and arranged within said recess, is the inner end of arod 29, upon which the coil spring is mounted. Secured to the outersides of the ears 10 of the stop plate 9, are the upwardly projectingspaced parallel posts 31, upon the uper ends of which is mounted a plate32 provided with a central opening through which the upper end of therod 29 is movable. It will be apparent from this that the coil spring 30is disposed between the plate 32 and the body of the hook member 27.From this it will be seen that the coil spring 30 will have a tendencyto press downwardly upon the hook member 27 and normally retain thetrolley pole 23 in a raised position, so that the wheel 24 will normallyengage the trolley wire.

After the cylinder 14 has been drawn within the cylinder 9, a pivotedlatch bar 33 is.

same from moving outwardly and forcing the trolley pole 23 downwardlytoward the guard and away from the trolley wire. The plate 33 isprovided with a tapering projection 36, the inner beveled side 37 ofwhich is adapted to be engaged by the hook 27 upon the downward movementof the same and thus releases the hooked end of the bar from the pin 35and permits outward sliding movement of the cylinder 14. It will beunderstood that upon the inward movement of the cylinder, the coilspring 15 is placed under tension, the tension 'of said spring forcingthe cylinder outwardly when released.

In Fig. 4, I have illustrated the device in a normally lowered'positionand when it is desired to raise the pole 23 to an operative position, sothat the trolley wheel 24 will on gage the trolley wire, the outer endof the cord 19 is pulled downwardly, thus reciprocating the rod 17within the cylinder 9 and pulling inwardly upon the cylinder 14, saidcylinder being pulled inwardly until the catch member 23 dropsdownwardly and en gages with the headed pin 35, thus retaining thecylinder 14 in its closed position and placing the spring 15 undertension. Should the trolley pole become accidentally detached from thewire, it will spring up wardly by means of the tension of the spring 30,thus the hook member 27 will engage with the tapering portion 37 of themember 36 and release the catch member 33, allowing the cylinder 14 toreciprocate outwardly by the tension of the spring 15 and in View of thefact that the outer end of the cylinder presses against the hook 27, itwill force downwardly upon the trolley pole 23 and return the same toits normal inoperative position.

From the above description taken in connection with the accompanyingdrawings, it will be apparent that I have provided a simple anddurabletrolley pole which is provided with means whereby the trolley pole isnormally retained into engagement with the trolley wire and should thesame become released, or disengaged from the trolley wire, it will beautomatically forced downwardly toward the top of the car. It will benoted that by having automatic means for returning the trolley poletoward the top of 5 the car, it will eliminate the danger of the polestriking against cross wires, bridges and the like and thus preserve theouter end of the pole. It will also be apparent that my improved deviceis extremely simple in construction and can be manufactured and placedupon the market at a comparatively low cost.

While I have shown and described the preferred form of my invention, itwill be obvious that various changes in the details of constructionandin the proportions may be resorted to for successfully carrying myinvention into practice, without sacrificing any of the novel featuresor departing from the scope of the invention, as defined by the appendedclaims.

Having thus described this invention, what I claim is r 1. A device ofthe, class described including a movable base, a stationary cylindercarried thereby, a movable cylinder arranged within one end of thestationary cylinder, a piston movable through the stationary cylinderand secured to the movable cylinder, a coil spring arranged within saidcylinders and adapted to be placed under tension upon the inwardmovement of the movable cylinder, a catch adapted to retain said movablecylinder within the stationary cylinder, a pivotally mounted trolleypole carried by the base and normally disposed in a raised position,spring actuated means for retaining said pole in its raised position,and means carried by the pole adapted to en- 12o gage the catch memberupon further upward movement of the pole, whereby to release the movablecylinder, the tension of said spring forcing the cylinder outwardlyagainst the inner end of the pole, whereby to lower the 12;; same to aninoperative position.
